A force acting on a 2.00 kg object is given by F(x) = (2.00 N/m)x + (1.00 N/m3)x3. An object starts at rest at x = 1.00 m. What is speed of the object when it reaches x = 2.00 m?
A)
1.23 m/s
B)
0.650 m/s
C)
2.60 m/s
D)
1.78 m/s
E)
The object does not reach 2.00 m because the increase in potential energy would imply a negative kinetic energy.
